To @ZZ whom it may'conocrn.-

Be it known that I, ROLAND RAKEsTRAw, a citizen of the United States, residing at Wyoming, in the county of Stark and State of Illinois, have invented certain new and useful Improvements in Rotary Harrows; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make anduse the same.

This invention relates toA rotary harrows.

The object of my invention is to provide a simple and substantial construction of the harroW-sections as well as the connections therefor, so that the said sections may be easily assembled and firmly connected together.

In the annexed drawings, Figure lis a plan View of the harrow, showing my improved construction. Fig. 2 is a perspective View of a section of the harrow. Fig. 3 is a perspective view of afour-armed center piece which forms a very important part of my invention. Fig. 4. is a perspective View of a portion of one of the harrow-sec-tions, showing means of constructing same. Fig. 5 is also a perspective view of a modified form of same. Fig. 6 is a perspective View of the weight attachment, showing two rollers for supporting and carrying same. Fig. 7 is a plan view of means of connecting two harrows together by a rod or beam somewhat forward of the center.

A A represent the four sections of the harrow, which are preferably made of lengths B B, of angle-iron, which are secured at their inner ends to the angle-iron C. The four bars of each sectionA diverge from the center of the harrow and are held in fixed relation to each other by a curved rodor track D, which is secured to each of the bars B by any good means in the position shown. A series of teeth are secured to the bars B in any good manner. A center piece for holding the sections in place when assembled is shown, and consists of a casting having four hollow arms E, and through the center of which is a vertical hole for receiving the kingbolt F, which holds in place the tongue G. Between the two middle bars of each section A is a bar or rod H, which is secured to the angle-piece C, the outer end of which is se-4 cured to a strip I, located somewhat behind the piece C. Each rod H is thus made rigid with its section A, leaving a portion of its forward end projecting beyond the piece O. The curved rod or track D passes over the top of the bars B, projecting somewhat beyond the outside ones, thence turns downward and passes back. again under the bars, 6o and terminates at itsstarting-point, thus forming a loop at either end. A hook D is hung in one of the loops thus formed, so that eachsection may be connected up with its neighbor.

. In Fig. 3 is shown the center piece, showing the hollow arms, while Fig. 4. shows means of securing the bars B to the angle-pieces C and I, simply using a block J for supporting the bar with a rivet or pin through the whole. 7o Fig. 5 shows also another method of placing and securing the angle-pieces in place. The methodlof construction, however, I do not of course strictly adhere to. Two arms K are secured to the tongue G, and their outer eX- 7 5 tremities carry a weight-box L, having a weight M. Beneath each end of theweightcarrier is a roller N, which runs npon the track- D. Veights are not new for use on harrows; but heretofore only one roller has Se been used, and when the weight had reached the connecting-hook between the sections A, as before stated, the weight would overhalance the sections and cause them to tilt up and thus twist the harrow and ending in a breakage or disarrangement ofparts, while with the double roller the Weight is distribnted on the sections, thiis holding them down at all times. f

In Fig..7 is shown the method of connect- 9o ing two harrows together by means of the beam O, which is located forward of the center and allows the harrows to move more freely and naturally than when connected at the center by the king-bolt. As usual, the weights are placed on opposite sides of the harrows in order to cause them to revolve in contrary directions.

It is obvious that more than four sections may be used in constructing this harrow and roo that various changes may be made, if desired.

In assembling the parts of the harrow it is only necessary to grasp each section A and insert its bar H into one of the hollow arms E, and after the sections are all placed the hooks D and the loops of the track D are connected and the device is complete.

Having thus described my invention,what

VI claim as new, and desire to secure by Letters arranged substantially as and for the purposes set forth and described.

2. In a rotary harrow the combination of the sections A of angle-iron, the track D secured thereto, the bars or rods H secured between the inner adjacent ends of the bars of said sections, the center portion having the hollow arms E for the entrance of the said rods H, the tongue G pivotally secured to the said center portion, the arms K secured to the tongue, the weight M with its rollers N, to run on said track D and the beam O secured to the tongue all substantially as and for the `purposes set forth and described.

In testimony whereof I aflix my signature in presence of two witnesses.
